在前面推文中我们分别介绍了独立样本t检验在jamovi(独立样本t检验(Independent Samples t-test)——jamovi软件实现)和SPSS(独立样本t检验(Independent Samples t-test)——SPSS软件实现)软件中的实现步骤,本篇推文将使用同样的案例演示在Stata软...
5.独立样本T检验Stata操作 6.单一样本T检验的R语言操作 1.独立样本T检验(Independent samples t test)的概念: 检验两组不相关的样本是否来自具有相同均值的总体。 例:(1)某地男女的平均收入是否相同,是否有显著差异; (2)学号前20名同学和学号后20名同学的英语成绩是否有显著差异。 独立样本T检验的概念示意图 2...

How do you test the equality of regression coefficients that are generated from two different regressions, estimated on two different samples? TitleTesting the equality of coefficients across independent areas AuthorAllen McDowell, StataCorp You must set up your data and regression model so that one ...
Hi there, I am trying to run a -chi2- chi-square test for two independent samples. I ran a test on two groups of students, groupA having more information than groupB. I would like to use the chi-square test in order to show that the differences in the answers by group1 compared ...
All samples were analyzed when internal quality control met the acceptance criteria. Hypertension was defined as systolic blood pressure (SBP) ≥ 140 mmHg, diastolic blood pressure (DBP) ≥ 90 mmHg or the use of anti-hypertensive drugs. Dyslipidemia was defined as TG ≥ 150 mg/...
For each permuted dataset, the top T SNPs are termed 'associated'. All SNP ratio statistics were calculated using custom scripts in STATA version 10 (Stata Corp., College Station, TX, USA). Gene tagging Individual SNP codes from the Illumina 1M Infinium SNP array platform were updated to ...
To achieve comparability between the experimental groups at baseline, the IG and CG will be compared in terms of sociodemographic characteristics. The independent samples Welch’st-test will be used for normally distributed metric variables, while the chi-square test will be employed for categorical ...

samples from prostate cancer patients with different disease stages (n = 25) as well as from healthy controls (n = 16) and patients with non-malignant diseases (n = 12). (P = 0.0001 for association between disease severity and CTC number, Kruskal–Wallis test). UTI: ...
